Ready for Summit.......
<center><img src="http://pictureposter.audiworld.com/21967/pa040001.jpg"></center><p>Finally got the FMIC installed. 2 stage boost controller connected, needs tuning. Side grilles no longer fit due to piping(modded S4 bumper for sale!) IC misters had to come out, didn't fit. BPV installed by throttle body. Straight pipe made from downpipe to '00 S4 cat back--makes 3" exhaust from turbo to tailpipe.
Will be at the track from Saturday through Tuesday. Dyno run at Curry's on Sunday, to redeem myself!
major improvement, stage 1 boost is at roughly 1.2 bar, stage 2 at around 1.5. Gotta hold on to the steering wheel, it really takes off! Stage 2 is no good until 2nd or 3rd gear, may even be slipping the (stock)clutch?
Much more to be done.....

Religous monitoring of gauges.....
Stoich & EGT's.....
Basically the chip(ATP's) is supposed to compensate for the readings from the MAF & 02 sensors. Supposed to "teach" itself, for different boost, race gas, etc.
I've got a bigger set of injectors, but haven't put them in yet. It's running rich at full boost-all the way up to 1.4 bar(highest I've seen). Egt's did get up to 950 though, kinda concerns me. Although the sensor is before the turbo, and the manifold and downpipe are ceramic coated, which may have an effect on that number. Any thoughts? Would the bigger injectors get even more fuel in--lowering the egt's? We'll see.

timing will also affect the EGTs....
Retarded timing will increase EGTs, and Advanced timing will lower EGTs. Of course, timing that is too advanced can cause detonation.
Bigger injectors will probably just cause the car to run like crap, unless you have the programming for them. My car runs good on 310's, but barely idles and is undriveable on 440's.

Depends on if the injector pulse is at max of 16.32ms
after that the maf readings dont matter anymore and I think the non dbw setup only uses the maf and 02 readings during part throttle while at wot you just go straight to the fuel maps. I know on the dbw when you go wot it uses the maf to adjust injector pulse.
Bigger injectors will just put more fuel in all the time. Making the car run bad during idle and part throttle, could even throw dtc's if it is more then 10% richer. When you put the new injectors in you will need the chip tuned to lower the pulse during that time.
